All of the kernel and C userspace code is open source and available from
linux-iscsi.org and licensed under the GPL.  There is the BSD licensed
code from userspace (iSNS), as well as ISCSI and SCSI MIBs.  As for what
pieces of code will be going upstream (for kernel and/or userspace), LIO
Target state machines and SE algoritims are definately some of the best
examples of GPL code for production IP storage fabric and has gained
maturity from people and resources applied to it in a number of
respects.

The LIO stack presents a number of possible options to get the diverse
amount of hardware and software to work.  Completely dismissing the
available code is certainly a waste, and there are still significant
amounts of functionality related to real-time administration, RFC-3720
MC/S and ERL=2 and generic SE functionality OS storage subsystems that
only exist in LIO and our assoicated projects.  A one obvious example is
the LIO-VM project, which brings LIO active-active transport recovery
and other Linux storage functionality to Vmware and Qemu images that can
provide target mode IP storage fabric on x86 non-linux based hosts.  A
first of its kind in the Linux/iSCSI universe.  

Anyways, lets get back to the technical discussion.
